offer and sell from time to time to Kingsbridge Capital Limited pursuant to the

securities exchange or market in which our common stock may in the future be
traded, in private negotiated transactions or otherwise. Kingsbridge Capital
Limited and Prentice Securities, Incorporated, the registered broker-dealer

Kingsbridge Capital Limited under the equity line, are "underwriters" within the
meaning of the Securities Act of 1933 in connection with such sales.

         Our common stock is traded on the Nasdaq National Market under the
symbol "CGPI." On April 24, 2002, the last reported sale price of our common
stock was $10.45 per share.

should consider before buying any shares of our common stock.

commission has approved or disapproved these securities, or passed upon the

                                 THE EQUITY LINE

         On February 14, 2002, we entered into a Common Stock Purchase
Agreement, or equity line arrangement with Kingsbridge Capital Limited, pursuant
to which we may issue and sell, from time to time, shares of our common stock
for cash consideration up to an aggregate of $8.5 million. Commencing as of such
date and continuing for twelve (12) months thereafter, we may, from time to
time, at our sole discretion, and subject to certain conditions that we must
satisfy, sell or "draw down", shares of our common stock to Kingsbridge at a
purchase price having a discount of up to 10% off of the daily volume weighted
average of the price of our common stock for each of the fifteen (15) days
during any specified purchase period as set forth in the following schedule:

                           VWAP*                            PERCENT OF VWAP
- -----------------------------------------------------------------------------
Equal to or greater than $15.00                                   94%
- -----------------------------------------------------------------------------
Equal to or greater than $7.00 but less than $15.00               92%
- -----------------------------------------------------------------------------
Greater than $3.34 but less than $7.00                            90%
- -----------------------------------------------------------------------------

         * As set forth in the equity line arrangement, "VWAP" means the volume
weighted average price of our common stock during a trading day as reported by
Bloomberg, L.P. using the AQR function.

         The maximum number of shares that we may issue under the equity line is
924,880, all of which shares are registered hereunder. An additional 40,000
shares are registered hereunder in connection with a warrant that we issued to
Kingsbridge in connection with the equity line. Unless agreed to in writing, we
may not sell shares at a per share price of less than $3.00. In addition, and
with certain exceptions, in the event we do not draw down an aggregate minimum
of $1.5 million under the equity line within six (6) months of February 14,
2002, we shall pay to Kingsbridge a cash amount equal to 10% of the amount by
which $1.5 million exceeds the actual amount of our draw downs during such six
(6) month period. We will exercise our right to draw down the equity line, to
the extent available, at such times as there is a need for additional capital
and when sales of stock under the equity line provide the most effective means
of raising capital.

         A draw down can be made after five (5) trading days have elapsed from
the date of expiration of the preceding draw down pricing period in amounts
ranging from a minimum of $250,000 to a maximum of $3,000,000, based upon our
then current market capitalization and as set forth in the following schedule:


             MARKET CAPITALIZATION                     MAXIMUM DRAW DOWN AMOUNT
- -------------------------------------------------------------------------------
             At least $150 million                            $3 million
- -------------------------------------------------------------------------------
At least $120 million but less than $150 million            $2.5 million
- -------------------------------------------------------------------------------
At least $90 million but less than $120 million               $2 million
- -------------------------------------------------------------------------------
At least $65 million but less than $90 million              $1.5 million
- -------------------------------------------------------------------------------
At least $45 million but less than $65 million                $1 million
- -------------------------------------------------------------------------------

         We may not deliver a draw down notice if the result to Kingsbridge
would be that, following the purchase of such shares, Kingsbridge or its
affiliates would beneficially own more than 9.9% of our common stock then
outstanding.

                                      -4-



         The issuance of our common stock under the equity line arrangement will
have no effect on the rights or privileges of existing holders of common stock
except that the economic and voting interests of each stockholder will be
diluted as a result of such issuance. Although the number of shares of common
stock that stockholders presently own will not decrease, such shares will
represent a smaller percentage of our total shares that will be outstanding
after such events. If we satisfy the conditions that allow us to draw down the
entire $8.5 million available under the equity line, and we choose to do so,
then generally, as the market price of our common stock decreases, the number of
shares we will have to issue increases, to a maximum of 924,880 shares.

         The following are all of the material additional conditions that must
be met before Kingsbridge Capital Limited is obligated to buy any shares of our
common stock upon delivery of a draw down notice, none of which are in the
control of Kingsbridge:

     o    Each  of  our  representations  and  warranties  in  the  equity  line
          agreement shall be true and correct in all material respects as of the
          date when made and as of the draw down exercise date as though made at
          that  time,  except  for   representations  and  warranties  that  are
          expressly made as of a particular date.

     o    The  registration  statement  registering  the  offer  and sale of our
          common stock shall remain effective and shall thereafter be amended or
          supplemented, as required, to disclose the then current sale of shares
          of our common stock.

     o    Trading  in our  common  stock  shall not have been  suspended  by the
          Securities  and  Exchange  Commission,  the Nasdaq Stock Market or the
          National  Association of Securities  Dealers and trading in our common
          stock shall not have been  suspended  or limited,  and minimum  prices
          shall  not have  been  established  on  securities  whose  trades  are
          reported  by the  American  Stock  Exchange  or  the  New  York  Stock
          Exchange.

     o    We shall have no  knowledge  of any event more likely than not to have
          the effect of causing the registration statement registering the offer
          and sale of the shares to be suspended or otherwise ineffective (which
          event is more likely than not to occur  within  fifteen  (15)  trading
          days  following  the  trading  day on  which  a draw  down  notice  is
          delivered).

     o    No material adverse effect shall have occurred.

         There is no guarantee that we will be able to meet these or any other
conditions under the equity line agreement or that we will be able to draw down
on any portion of the $8,500,000 equity line.


                                      -5-



                                  RISK FACTORS

         Investing in our common stock involves a high degree of risk. You
should carefully consider the risks and uncertainties described below before
purchasing our common stock. The risks and uncertainties described below are all
of the material risks of which we are aware. If any of the following risks
actually occur, our business, financial condition or results of operations would
likely suffer. In that case, the trading price of our common stock could fall,
and you may lose all or part of the money you paid to buy our common stock.

         IF PERIOSTAT IS NOT ADOPTED ROUTINELY BY DENTAL PROFESSIONALS OR IF
MANAGED CARE PROVIDERS DO NOT CONTINUE TO REIMBURSE PATIENTS, OUR SALES GROWTH
WILL SUFFER.

         Our growth and success depends in large part on our ability to continue
to demonstrate the safety and effectiveness of Periostat for the treatment of
gum disease to dental practitioners. Periostat is the first long-term medical
therapy for any dental disease and dentists are not accustomed to prescribing
drugs for a minimum 90-day duration. Periostat works by suppressing certain
enzymes involved in the periodontal disease process, which is a new concept for
many dentists who believe that removing bacterial plaque is the only way to
treat this disease. Accordingly, our sales efforts are largely focused on
educating dental professionals about an entirely new approach to treating
periodontitis. Although over 35,000 dentists in the United States have written
at least one prescription for Periostat, a number of dentists have not adopted
Periostat routinely into their treatment of adult periodontitis. Other dentists
have prescribed Periostat for only a subset of their eligible patients,
typically their most advanced or refractory cases. If we are unable to initiate
and/or expand usage of Periostat by dentists, our sales growth will suffer.

         Approximately 65% of the large managed care providers in the United
States (defined as those that cover 100,000 or more lives) reimburse their
patients for Periostat, typically requiring a modest co-payment. Our goal is to
achieve reimbursement from approximately 75% of the large managed care
providers, since the remainder have policies that do not reimburse for drugs to
treat dental conditions. Patients who are not reimbursed by managed care
providers may choose not to accept Periostat as a treatment.

         WE RELY ON PERIOSTAT FOR MOST OF OUR REVENUE.

         During 1999, Periostat accounted for 95% of our total net revenues.
During 2000, Periostat accounted for 84% of our total net revenues. During 2001,
Periostat accounted for approximately 87% of our total net revenues. Although we
currently derive additional revenue from marketing and/or selling other products
(Vioxx(R), Atridox, Atrisorb FreeFlow and Atrisorb-D) and from licensing fees
from foreign marketing partners, our revenue and profitability in the near
future will depend on our ability to successfully market and sell Periostat.

         WE ANTICIPATE FUTURE LOSSES.

         From our founding in 1992 through the commercial launch of Periostat in
November, 1998, we had no revenue from sales of our own products. During the
year ended December 31, 2000, we experienced a net loss of approximately $8.8
million. During the year ended December 31, 2001, we experienced a net loss of
approximately $8.1 million. From inception through December 31, 2001, we have
experienced an aggregate net loss of $69.5 million. Our historical losses have
resulted primarily from the expenses associated with our pharmaceutical
development program, clinical trials, the regulatory approval process associated
with Periostat and sales and marketing activities relating to Periostat. We
expect to incur significant future expenses, particularly with respect to the
sales and marketing of Periostat. As a result, we anticipate losses at least
through the second quarter of 2002.

                                      -6-



         WE HAVE A LIMITED MARKETING AND SALES HISTORY AND MAY NOT BE ABLE TO
SUCCESSFULLY MARKET OUR PRODUCT CANDIDATES.

         We have a limited history of marketing, distributing and selling
pharmaceutical products in the dental market. In January 1999, we first trained
a sales force of sales representatives and managers and began to promote
Periostat to the dental community. We market and sell our products in the United
States through this direct sales force. Furthermore, we have entered into
agreements to market Periostat, upon receipt of the necessary foreign regulatory
approvals, in certain countries in Europe, Israel, Japan, Canada and the Middle
East, and we continue to evaluate partnering arrangements in other countries
outside the United States. If we are unable to continue to recruit, train and
retain sales and marketing personnel, we will be unable to successfully expand
our sales and marketing efforts. Furthermore, if our foreign partners do not
devote sufficient resources to perform their contractual obligations with us, we
may not achieve our foreign sales goals. Pursuant to an exclusive Licensing and
Marketing Agreement with Atrix Laboratories, Inc., we began marketing Atrix's
proprietary dental products, Atridox(R), Atrisorb(R) FreeFlow and Atrisorb(R)-D,
to the United States dental market in October 2001. It is too early to determine
whether there will be sufficient acceptance of these products to achieve or
maintain profitability.

         OUR COMPETITIVE POSITION IN THE MARKETPLACE DEPENDS ON ENFORCING AND
SUCCESSFULLY DEFENDING OUR INTELLECTUAL PROPERTY RIGHTS.

         In order to be competitive in the pharmaceutical industry, it is
important to establish, enforce, and successfully defend patent and trade secret
protection for our established and new technologies. We must also avoid
liability from infringing the proprietary rights of others.

         Our core technology is licensed from The Research Foundation of the
State University of New York ("SUNY"), and other academic and research
institutions collaborating with SUNY. Under the license agreement with SUNY (the
"SUNY License") we have an exclusive worldwide license to SUNY's rights in
certain patents and patent applications to make and sell products employing
tetracyclines to treat certain disease conditions. The SUNY License imposes
various payment and reporting obligations on us and our failure to comply with
these requirements permits SUNY to terminate the SUNY License. If the SUNY
License is terminated, we would lose our right to exclude competitors from
commercializing similar products, and we could be excluded from marketing the
same products if SUNY licensed the underlying technology to a competitor after
terminating the SUNY License.

         SUNY owns thirty (30) United States patents and three (3) United States
patent applications that are licensed to us. The patents licensed from SUNY
expire between 2004 and 2018. Two of the patents are related to Periostat and
expire in 2004 and 2007. Technology covered by these patents becomes available
to competitors as the patents expire.

         Since many of our patent rights cover new treatments using
tetracyclines, which are generally available for their known use as antibiotics,
we may be required to bring expensive infringement actions to enforce our
patents and protect our technology. Although federal law prohibits making and
selling pharmaceuticals for infringing use, competitors and/or practitioners may
provide generic forms of tetracycline for treatment(s) which infringe our
patents, rather than prescribe our Periostat product. Enforcement of patents can
be expensive and time consuming.

         Our success also depends upon know-how, trade secrets, and the skills,
knowledge and experience of our scientific and technical personnel. To that end,
we require all of our employees and, to the extent possible, all consultants,
advisors and research collaborators, to enter into confidentiality agreements
prohibiting unauthorized disclosure. With respect to information and chemical
compounds

                                      -7-


we provide for testing to collaborators in academic institutions, we cannot
guarantee that the institutions will not assert property rights in the results
of such tests nor that a license can be reasonably obtained from such
institutions which assert such rights. Failure to obtain the benefit of such
testing could adversely affect our commercial position and, consequently, our
financial condition.

         IF WE LOSE OUR SOLE SUPPLIER OF DOXYCYCLINE OR OUR CURRENT MANUFACTURER
OF PERIOSTAT, OUR COMMERCIALIZATION OF PERIOSTAT WILL BE INTERRUPTED OR LESS
PROFITABLE.

         We rely on a single supplier, Hovione International Limited
("Hovione"), for doxycycline, the active ingredient in Periostat. There are
relatively few alternative suppliers of doxycycline and Hovione produces the
majority of the doxycycline used in the United States. Our current supply
agreement with Hovione expires on May 14, 2006 and thereafter automatically
renews for successive two-year periods unless, ninety (90) days prior to the
expiration of any such periods, either party gives the other party written
notice of termination. In addition, in the event of a default, uncured for
ninety (90) days, the non-defaulting party can terminate the supply agreement
effective immediately at the end of such 90-day period. We rely on Hovione as
our sole supplier of doxycycline and have no back-up supplier at this time. If
we are unable to procure a commercial quantity of doxycycline from Hovione on an
ongoing basis at a competitive price, or if we cannot find a replacement
supplier in a timely manner or with favorable pricing terms, our costs may
increase significantly and we may experience delays in the supply of Periostat.

         We historically relied on a single third-party contract manufacturer,
Applied Analytical Industries, Inc., ("AAI") to produce Periostat in a capsule
formulation. AAI served notice of its intent to terminate its agreement to
supply Periostat capsules to us as of November 2001. The agreement with AAI
provided for AAI to commit to an additional twelve (12) months supply of product
at a price premium, should we be unable to qualify an alternative manufacturing
source subsequent to the termination of the AAI agreement. As an alternative,
and in an effort to capitalize on certain manufacturing cost advantages, in July
2001, we launched our new tablet formulation of Periostat which has now replaced
our capsule formulation of Periostat. We believe that the change to a tablet
formulation will positively impact our results of operations by improving our
gross margin on Periostat sales from approximately 79% to approximately 88% of
Periostat net sales. We have entered into an agreement with a contract
manufacturer, Pharmaceutical Manufacturing Research Services, Inc. ("PMRS"), for
such tablet formulation for Periostat, and we are, therefore, no longer
dependent upon, nor do we utilize, AAI. We have fulfilled our initial purchase
orders with PMRS and expect to make certain purchases from PMRS through 2002.
Currently, PMRS is the sole third-party contract manufacturer to supply a tablet
formulation of Periostat to us. Any inability of PMRS to produce and supply
product on agreed upon terms could result in delays in the supply of Periostat.
We also intend to contract with additional manufacturers for the commercial
manufacture of Periostat tablets. We believe, however, that it could take up to
one (1) year to successfully transition from PMRS to a new manufacturer.

         OUR PRODUCTS ARE SUBJECT TO EXTENSIVE REGULATION BY THE FDA.

         Drugs and medical devices generally require approval or clearance from
the FDA before they can be marketed in the United States. Periostat, Vioxx(R),
and Atridox(R) have been approved by the FDA as drugs. Atrisorb(R) FreeFlow and
Atrisorb(R)-D have been cleared by the FDA as medical devices. Our drug products
under development, however, will have to be approved by the FDA before they can
be marketed in the United States. If the FDA does not approve our products in a
timely fashion, or does not approve them at all, our financial condition may be
adversely affected.

         In addition, drug and medical device products remain subject to
comprehensive regulation by the FDA while they are being marketed. The drug and
medical device regulatory schemes differ in detail, but

                                      -8-


they are essentially similar. The FDA regulates, for example, the safety,
manufacturing, labeling, and promotion of both drug and medical device products.
Although Dentaplex, a dietary supplement, did not require FDA approval prior to
marketing, it is also subject to regulation while it is being marketed. If we
or our partners who manufacture our products fail to comply with regulatory
requirements, various adverse consequences can result, including recalls, civil
penalties, withdrawal of the product from the market and/or the imposition of
civil or criminal sanctions.

         We are, and will increasingly be, subject to a variety of foreign
regulatory regimes governing clinical trials and sales of our products. Other
than Periostat, which has been approved by the Medicines Control Agency for
marketing in the United Kingdom, our products in development have not been
approved in any foreign country. Whether or not FDA approval has been obtained,
approval of drug products by the comparable regulatory authorities of foreign
countries must be obtained prior to the commencement of marketing of those
products in those countries. The approval process varies from country to country
and other countries may also impose post-approval requirements. Other countries
may also impose regulatory requirements on dietary supplements.

         IF OUR PRODUCTS CAUSE INJURIES, WE MAY INCUR SIGNIFICANT EXPENSE
AND LIABILITY.

         Our business may be adversely affected by potential product liability
risks inherent in the testing, manufacturing and marketing of Periostat and
other products developed by or for us or for which we have licensing or
co-promotion rights. We have $10.0 million in product liability insurance for
Periostat. This level of insurance may not adequately protect us against product
liability claims. Insufficient insurance coverage or the failure to obtain
indemnification from third parties for their respective liabilities may expose
us to product liability claims and/or recalls and could cause our business,
financial condition and results of operations to decline.

         IF WE NEED ADDITIONAL FINANCING, AND FINANCING IS UNAVAILABLE, OUR
ABILITY TO DEVELOP AND COMMERCIALIZE PRODUCTS AND OUR OPERATIONS WILL BE
ADVERSELY AFFECTED.

         We have historically financed our operations through public and private
equity financings. Our capital requirements depend on numerous factors,
including our ability to successfully commercialize Periostat, competing
technological and market developments, our ability to enter into collaborative
arrangements for the development, regulatory approval and commercialization of
other products, and the cost of filing, prosecuting, defending and enforcing
patent claims and other intellectual property rights. We anticipate that we may
be required to raise additional capital in order to conduct our operations.
Additional funding, if necessary, may not be available on favorable terms, if at
all. If adequate funds are not available, we may be required to curtail
operations significantly or to obtain funds through arrangements with
collaborative partners or others that may require us to relinquish rights to
certain of our technologies, product candidates, products or potential markets.
At December 31, 2001 we had cash, cash equivalents and short-term investments of
approximately $6.2 million. In March 2001, we raised approximately $6.8 million,
net of offering costs, through the sale of our common stock and warrants to
purchase shares of our common stock. In August 2001, we raised approximately
$3.0 million through the sale of unregistered shares of our common stock to
Atrix Laboratories, Inc. in connection with our entering into certain licensing
arrangements with Atrix. We anticipate that our existing working capital will be
sufficient to fund our current operations through at least the end of 2002.
However, we may seek additional funding to expand our current operations through
the acquisition of additional products or by investing in the development of our
research and development pipeline.

                                      -9-


         BECAUSE OUR EXECUTIVE OFFICERS, DIRECTORS AND AFFILIATED ENTITIES OWN
APPROXIMATELY 34.5% OF OUR CAPITAL STOCK, THEY COULD CONTROL OUR ACTIONS IN A
MANNER THAT CONFLICTS WITH OUR INTERESTS AND THE INTERESTS OF OUR OTHER
STOCKHOLDERS.

         Currently, our executive officers, directors and affiliated entities
together beneficially own approximately 34.5% of the outstanding shares of our
common stock or equity securities convertible into common stock. As a result,
these stockholders, acting together, or in the case of our preferred
stockholders, in certain instances, as a class, will be able to exercise control
over corporate actions requiring stockholder approval, including the election of
directors. This concentration of ownership may have the effect of delaying or
preventing a change in control, including transactions in which our stockholders
might otherwise receive a premium for their shares over then current market
prices.

         WE EXPECT TO SELL SHARES OF OUR COMMON STOCK IN THE FUTURE, INCLUDING
SHARES ISSUED UNDER OUR EQUITY LINE WITH KINGSBRIDGE CAPITAL LIMITED AND THESE
SALES WILL DILUTE THE INTERESTS OF SECURITY HOLDERS AND DEPRESS THE PRICE OF OUR
COMMON STOCK.

         As of December 31, 2001, there were 10,999,573 shares of our common
stock outstanding, options to purchase approximately 2,452,609 shares of our
common stock outstanding, and there were outstanding warrants to purchase
approximately 550,000 shares of our common stock outstanding. There are also
924,880 shares of common stock which, upon effectiveness of our shelf
registration statement, are issuable under the equity line with Kingsbridge and
40,000 shares issuable under the warrants which we granted to Kingsbridge in
connection with the equity line arrangement. We may also issue additional shares
in acquisitions, financings or in connection with the grant of additional stock
options to our employees, officers, directors or consultants under our stock
option plans.

         The issuance or even the potential issuance of shares under the equity
line, in connection with any other additional financing, and upon exercise of
warrants, options or rights will have a dilutive impact on other stockholders
and could have a negative effect on the market price of our common stock. In
addition, if we draw down under the equity line, we will issue shares to
Kingsbridge at a discount to the daily volume weighted average prices of our
common stock during the fifteen (15) trading days after notification of a
drawdown. This will further dilute the interests of the other stockholders.

         If we draw down on the equity line when share prices are decreasing, we
will need to issue more shares, which will lead to dilution and potentially
further price decrease.

         As we sell shares of our common stock to Kingsbridge under the equity
line and then Kingsbridge sells the common stock to third parties, our common
stock price may decrease due to the additional shares in the market. If we
decide to draw down on the equity line as the price of our common stock
decreases, we will need to issue more shares of our common stock for any given
dollar amount that Kingsbridge invests, subject to the minimum selling price we
specify. The perceived risk of dilution from sales of stock to Kingsbridge may
cause holders of our common stock to sell their shares, or it may encourage
short sales. This could contribute to a decline in our share price. Kingsbridge
has covenanted in the equity line arrangement that neither Kingsbridge nor any
of its affiliates nor any entity managed by Kingsbridge will ever be in a net
short position with respect to shares of our common stock in any accounts
directly or indirectly managed by any such person or entity. The more shares
that we issue under the equity line of credit, the more diluted our shares will
be and the more our stock price may decrease. This may encourage short sales,
which could place further downward pressure on the price of our common stock.

                                      -10-


         OUR STOCK PRICE IS HIGHLY VOLATILE, AND THEREFORE THE VALUE OF YOUR
INVESTMENT MAY FLUCTUATE SIGNIFICANTLY.

         The market price of our common stock has fluctuated and may continue to
fluctuate as a result of variations in our quarterly operating results. These
fluctuations may be exaggerated if the trading volume of our common stock is
low. In addition, the stock market in general has experienced dramatic price and
volume fluctuations from time to time. These fluctuations may or may not be
based upon any business or operating results. Our common stock may experience
similar or even more dramatic price and volume fluctuations which may continue
indefinitely.

         The following table sets forth the high and low closing market price
for our common stock for each of the quarters in the period beginning January 1,
1999 through March 31, 2002 as reported on the Nasdaq National Market:

               SPECIAL NOTE REGARDING FORWARD-LOOKING INFORMATION

         This prospectus and the documents incorporated herein contain
forward-looking statements within the meaning of Section 27A of the Securities
Act of 1933, as amended, and Section 21E of the Securities and Exchange Act of
1934, as amended. For this purpose, any statements contained herein or
incorporated herein that are not statements of historical fact may be
forward-looking statements. For example, the words "may," "will," "continue,"
"believes," "expects," "anticipates," "intends," "estimates," "should" and
similar expressions are intended to identify forward-looking statements. There
are a number of important factors that could cause CollaGenex's results to
differ materially from those indicated by such forward-looking statements. These
factors include those set forth in the section entitled "Risk Factors." In
particular, CollaGenex's business of selling, marketing and developing
pharmaceutical products is subject to a number of significant risks, including
risks relating to the implementation of CollaGenex's sales and marketing plans
for Periostat(R) and other products that we market, risks inherent in research
and development activities, risks associated with conducting business in a
highly regulated environment and uncertainty relating to clinical trials of
products under development. CollaGenex's success depends to a large degree upon
the market acceptance of Periostat by periodontists, dental practitioners, other
health care providers, patients and insurance companies. There can be no
assurance that CollaGenex's product candidates (other than the FDA's approval of
Periostat for marketing in the

                                      -11-



United States and the United Kingdom Medicines Control Agency's approval of
Periostat for marketing in the United Kingdom) will be approved by any
regulatory authority for marketing in any jurisdiction or, if approved, that
any such products will be successfully commercialized by CollaGenex. In
addition, there can be no assurance that CollaGenex will successfully
commercialize Dentaplex(TM), Vioxx(R), Atridox(R), Atrisorb(R)-Free Flow
and Atrisorb(R)-D. As a result of such risks and others expressed from time
to time in CollaGenex's filings with the Securities and Exchange Commission,
CollaGenex's actual results may differ materially from the results discussed in
or implied by the forward-looking statements contained herein.

                                 USE OF PROCEEDS

         We will receive all of the net proceeds from the sale of our securities
registered under the registration statement of which this prospectus is a part.

         Unless the applicable prospectus supplement states otherwise, we will
retain broad discretion in the allocation of the net proceeds of this offering.
We currently intend to use the net proceeds of this and any future issuances
for:

     o    research and development of additional products;

     o    expansion of our sales and marketing capabilities;

     o    potential product acquisitions; and

     o    other  general  corporate  purposes,   including  principally  working
          capital and capital expenditures.

         We have not determined the amount of net proceeds to be used for each
of the specific purposes indicated. The amounts and timing of the expenditures
may vary significantly depending on numerous factors, such as the progress of
our research and development efforts, technological advances and the competitive
environment for our products. Accordingly, we will have broad discretion to use
the proceeds as we see fit. Pending such uses, we intend to invest the net
proceeds in interest-bearing, investment grade securities.

                              PLAN OF DISTRIBUTION

         We have not yet issued or sold any shares of our common stock under
this Registration Statement on Form S-3.

         We are offering up to 924,880 shares of our common stock to Kingsbridge
Capital Limited which has obligated itself, subject to certain conditions, to
purchase such shares pursuant to this registration statement. The common stock
will be purchased pursuant to the terms of a Common Stock Purchase Agreement, or
equity line arrangement that we entered into with Kingsbridge on February 14,
2002. The terms and conditions of the equity line arrangement are more fully
described herein beginning on page 4 under the title "The Equity Line." An
additional 40,000 shares of common stock underlying a warrant we issued to
Kingsbridge in connection with the equity line are also registered hereunder.

         Kingsbridge Capital Limited and Prentice Securities, Incorporated, the
registered broker-dealer through which Kingsbridge Capital Limited intends to
sell the shares acquired by Kingsbridge Capital Limited under the equity line,
are "underwriters" within the meaning of the Securities Act of 1933 in

                                      -12-


connection with such sales. Prior to entering into the equity line arrangement
with us, Kingsbridge did not own any shares of our common stock.

         Upon the sale of shares under this registration statement, the
securities registered by this registration statement will be freely tradable in
the hands of persons other than our affiliates. Kingsbridge has covenanted in
the equity line arrangement that neither Kingsbridge nor any of its affiliates
nor any entity managed by Kingsbridge will ever be in a net short position with
respect to shares of our common stock in any accounts directly or indirectly
managed by any such person or entity.

         We agreed, under the terms of the Common Stock Purchase Agreement by
and between us and Kingsbridge Capital Limited to indemnify and hold harmless
Kingsbridge Capital Limited, each person, if any, who controls Kingsbridge
Capital Limited within the meaning of Section 15 of the Securities Act of 1933,
as amended, and each officer, director, employee and agent of Kingsbridge
Capital Limited and of any such controlling person against any and all
liabilities, claims, damages or expenses whatsoever, as incurred, arising out of
or resulting from any breach or alleged breach or other violation of any
representation, warranty, covenant or undertaking by us contained in such Common
Stock Purchase Agreement. We have agreed to reimburse Kingsbridge Capital
Limited for its reasonable legal and other expenses (including the reasonable
cost of any investigation and preparation, and including the reasonable fees and
expenses of counsel) incurred in connection therewith.

                                  LEGAL MATTERS

         The validity of the shares of common stock offered hereby will be
passed upon by Hale and Dorr LLP, Princeton, New Jersey.

                    INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Subsection (a) of Section 145 of the Delaware General Corporation Law
empowers a corporation to indemnify any person who was or is threatened to be
made a party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative (other than an action
by or in the right of the corporation) by reason of the fact that he or she is
or was a director, officer, employee or agent of the corporation, or is or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by him or her in
connection with such action, suit or proceeding if he or she acted in good faith
and in a manner he or she reasonably believed to be in or not opposed to the
best interests of the corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his or her conduct was unlawful.

         Subsection (b) of Section 145 empowers a corporation to indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that he or
she is or was a director, officer, employee or agent of the corporation, or is
or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise, against expenses (including attorneys' fees) actually and
reasonably incurred by him or her in connection with the defense or settlement
of such action or suit if he or she acted in good faith and in a manner he or
she reasonably believed to be in or not opposed to the best interests of the
corporation and except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the corporation unless and only to the extent that the Court of
Chancery or the court in which such action or suit was brought shall determine
upon application that, despite the adjudication of liability but in view of all
of the circumstances of the case, such person is fairly and reasonably entitled
to indemnity for such expenses which the Court of Chancery or such other court
shall deem proper.

         Section 145 further provides that to the extent a director or officer
of a corporation has been successful in the defense of any action, suit or
proceeding referred to in subsection (a) and (b) or in the defense of any claim,
issue or matter therein, he or she shall be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by him or her in
connection therewith; that the indemnification provided by Section 145 shall not
be deemed exclusive of any other rights to which the indemnified party may be
entitled; and that the scope of indemnification extends to directors, officers,
employees, or agents of a constituent corporation absorbed in a consolidation or
merger and persons serving in that capacity at the request of the constituent
corporation for another. Section 145 also empowers a corporation to purchase and
maintain insurance on behalf of a director or officer of the corporation against
any liability asserted against him or her or incurred by him or her in any such
capacity or arising out of his or her status as such whether or not the
corporation would have the power to indemnify him or her against such
liabilities under Section 145.

         Article IX of CollaGenex's By-laws specifies that CollaGenex shall
indemnify its directors, officers, employees and agents because he or she was or
is a director, officer, employee or agent of the Corporation or was or is
serving at the request of the Corporation as a director, officer, employee or
agent of another entity to the full extent that such right of indemnity is
permitted by the laws of the State of Delaware. This provision of the By-laws is
deemed to be a contract between CollaGenex and each director and officer who
serves in such capacity at any time while such provision and the relevant
provisions of the Delaware General Corporation Law are in effect, and any repeal
or modification thereof shall not offset any action, suit or proceeding
theretofore or thereafter brought or threatened based in whole or in part upon
any such state of facts. The affirmative vote of the holders of at least 80% of
the
                                      -15-


voting power of all outstanding shares of the capital stock of CollaGenex,
and, in certain circumstances, 66 2/3% of the voting power of all outstanding
shares of the Series D cumulative convertible preferred stock of CollaGenex,
is required to adopt, amend or repeal such provision of the By-laws.

         CollaGenex has executed indemnification agreements with each of its
officers and directors pursuant to which CollaGenex has agreed to indemnify such
parties to the full extent permitted by law, subject to certain exceptions, if
such party becomes subject to an action because such party is a director,
officer, employee, agent or fiduciary of CollaGenex.

         Section 102(b)(7) of the Delaware General Corporation Law enables a
corporation in its certificate of incorporation to limit the personal liability
of members of its board of directors for violation of a director's fiduciary
duty of care. This section does not, however, limit the liability of a director
for breaching his or her duty of loyalty, failing to act in good faith, engaging
in intentional misconduct or knowingly violating a law, or from any transaction
in which the director derived an improper personal benefit. This section also
will have no effect on claims arising under the federal securities laws.

         CollaGenex's Amended and Restated Certificate of Incorporation limits
the liability of its directors as authorized by Section 102(b)(7). The
affirmative vote of the holders of at least 75% of the voting power of all
outstanding shares of the capital stock of CollaGenex, and, in certain
circumstances, 66 2/3% of the voting power of all outstanding shares of the
Series D cumulative convertible preferred stock of CollaGenex, is required to
amend such provisions.

         CollaGenex has obtained liability insurance for the benefit of its
directors and officers which provides coverage for losses of directors and
officers for liabilities arising out of claims against such persons acting as
directors or officers of CollaGenex (or any subsidiary thereof) due to any
breach of duty, neglect, error, misstatement, misleading statement, omission or
act done by such directors and officers, except as prohibited by law.

Item 15. Indemnification of Directors and Officers.


         Subsection (a) of Section 145 of the Delaware General Corporation Law
empowers a corporation to indemnify any person who was or is threatened to be
made a party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative (other than an action
by or in the right of the corporation) by reason of the fact that he or she is
or was a director, officer, employee or agent of the corporation, or is or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by him or her in
connection with such action, suit or proceeding if he or she acted in good faith
and in a manner he or she reasonably believed to be in or not opposed to the
best interests of the corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his or her conduct was unlawful.

         Subsection (b) of Section 145 empowers a corporation to indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that he or
she is or was a director, officer, employee or agent of the corporation, or is
or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise, against expenses (including attorneys' fees) actually and
reasonably incurred by him or her in connection with the defense or settlement
of such action or suit if he or she acted in good faith and in a manner he or
she reasonably believed to be in or not opposed to the best interests of the
corporation and except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the corporation unless and only to the extent that the Court of
Chancery or the court in which such action or suit was brought shall determine
upon application that, despite the adjudication of liability but in view of all
of the circumstances of the case, such person is fairly and reasonably entitled
to indemnity for such expenses which the Court of Chancery or such other court
shall deem proper.

         Section 145 further provides that to the extent a director or officer
of a corporation has been successful in the defense of any action, suit or
proceeding referred to in subsection (a) and (b) or in the defense of any claim,
issue or matter therein, he or she shall be indemnified against expenses
(including

                                      II-1



attorneys' fees) actually and reasonably incurred by him or her in connection
therewith; that the indemnification provided by Section 145 shall not be deemed
exclusive of any other rights to which the indemnified  party may be entitled;
and that the scope of indemnification extends to directors, officers, employees,
or agents of a constituent corporation absorbed in a consolidation or merger and
persons serving in that capacity at the request of the constituent corporation
for another.  Section 145 also empowers a corporation to purchase and maintain
insurance on behalf of a director or officer of the corporation against any
liability asserted against him or her or incurred by him or her in any such
capacity or arising out of his or her status as such whether  or not  the
corporation would have the power to indemnify him or her against  such
liabilities under Section 145.

         Article IX of CollaGenex's By-laws specifies that CollaGenex shall
indemnify its directors, officers, employees and agents because he or she was or
is a director, officer, employee or agent of CollaGenex or was or is serving at
the request of CollaGenex as a director, officer, employee or agent of another
entity to the full extent that such right of indemnity is permitted by the laws
of the State of Delaware. This provision of the By-laws is deemed to be a
contract between CollaGenex and each director and officer who serves in such
capacity at any time while such provision and the relevant provisions of the
Delaware General Corporation Law are in effect, and any repeal or modification
thereof shall not offset any action, suit or proceeding theretofore or
thereafter brought or threatened based in whole or in part upon any such state
of facts. The affirmative vote of the holders of at least 80% of the voting
power of all outstanding shares of the capital stock of CollaGenex, and, in
certain circumstances, 66 2/3% of the voting power of all outstanding shares of
the Series D cumulative convertible preferred stock of CollaGenex, is required
to adopt, amend or repeal such provision of the By-laws.

         CollaGenex has executed indemnification agreements with each of its
officers and directors pursuant to which CollaGenex has agreed to indemnify such
parties to the full extent permitted by law, subject to certain exceptions, if
such party becomes subject to an action because such party is a director,
officer, employee, agent or fiduciary of CollaGenex.

         Section 102(b)(7) of the Delaware General Corporation Law enables a
corporation in its certificate of incorporation to limit the personal liability
of members of its board of directors for violation of a director's fiduciary
duty of care. This section does not, however, limit the liability of a director

in which the director derived an improper personal benefit. This section also

outstanding shares of the capital stock of CollaGenex, and, in certain
circumstances, 66 2/3% of the voting power of all outstanding shares of the

amend such provisions.

         CollaGenex has obtained liability insurance for the benefit of its

directors or officers of CollaGenex (or any subsidiary thereof) due to any

Item 17. Undertakings.

         The undersigned Registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this Registration Statement:

          (i) To include  any  prospectus  required  by Section  10(a)(3) of the
     Securities Act of 1933, as amended (the "Securities Act");

          (ii) To reflect in the  prospectus  any facts or events  arising after
     the  effective  date of this  Registration  Statement  (or the most  recent
     post-effective amendment thereof) which,  individually or in the aggregate,
     represent  a  fundamental  change  in the  information  set  forth  in this
     Registration  Statement.  Notwithstanding  the  foregoing,  any increase or
     decrease  in volume of  securities  offered (if the total  dollar  value of
     securities  offered  would not exceed  that which was  registered)  and any
     deviation from the low or high end of the estimated  maximum offering range
     may be  reflected  in the form of  prospectus  filed  with  the  Commission
     pursuant  to Rule  424(b) if, in the  aggregate,  the changes in volume and
     price represent no more than 20% change in the maximum  aggregate  offering
     price set  forth in the  "Calculation  of  Registration  Fee"  table in the
     effective Registration Statement; and

          (iii) To include any material  information with respect to the plan of
     distribution not previously disclosed in this Registration Statement or any
     material change to such information in this Registration Statement;

provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by the Registrant pursuant to Section 13 or Section 15(d) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), that are
incorporated by reference in this Registration Statement.

     (2)  That,  for  the  purposes  of  determining  any  liability  under  the
Securities  Act,  each  post-effective  amendment  shall be  deemed  to be a new
registration  statement  relating to the  securities  offered  therein,  and the
offering of such  securities  at the time shall be deemed to be the initial bona
fide offering thereof.

                                      II-3


     (3) To remove from registration by means of a post-effective  amendment any
of the securities being registered which remain unsold at the termination of the
offering.

         The Registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the Registrant's annual
report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Exchange Act) that is incorporated by reference in this
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the indemnification provisions described herein, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
